Claims

[Claim for Utility Model Registration] A hysteresis ring made of ring-shaped hysteresis strips is provided on the inner circumferential surface of the cylindrical portion of the reel stand main body, and a magnetic structure in which different magnetic poles are arranged alternately in the circumferential direction is used for the hysteresis ring. In the reel stand device, the magnet structure is fixedly arranged inside a ring so as to face the hysteresis ring at a distance, and the magnet structure and the rotating hysteresis ring cooperate to apply a braking force to the rotation of the reel stand main body. , the hysteresis strip has a shape having a convex portion at one end and a concave portion having a shape corresponding to the convex portion at the other end, and the hysteresis ring is configured such that the convex portion and the concave portion fit together. A reel stand device having a structure formed by joining together.
